Installing GNU Fortran
|
||||
**********************
|
||||
|
||||
The following information describes how to install `g77'.
|
||||
|
||||
Note that, for users of the GCC-2.95 version of `g77', much of the
|
||||
information is obsolete, and is superceded by the GCC installation
|
||||
procedures. Such information is accordingly omitted and flagged as
|
||||
such.
|
||||
|
||||
*Warning:* The information below is still under development, and
|
||||
might not accurately reflect the `g77' code base of which it is a part.
|
||||
Efforts are made to keep it somewhat up-to-date, but they are
|
||||
particularly concentrated on any version of this information that is
|
||||
distributed as part of a *released* `g77'.
|
||||
|
||||
In particular, while this information is intended to apply to the
|
||||
GCC-2.95 version of `g77', only an official *release* of that version
|
||||
is expected to contain documentation that is most consistent with the
|
||||
`g77' product in that version.
|
||||
|
||||
The following information was last updated on 1999-07-17:
|
||||
|
||||
Prerequisites
|
||||
=============
|
||||
|
||||
For users of the GCC-2.95 version of `g77', this information is
|
||||
superceded by the GCC installation instructions.
|
||||
|
||||
Problems Installing
|
||||
===================
|
||||
|
||||
This is a list of problems (and some apparent problems which don't
|
||||
really mean anything is wrong) that show up when configuring, building,
|
||||
installing, or porting GNU Fortran.
|
||||
|
||||
*Note Installation Problems: (gcc)Installation Problems, for more
|
||||
information on installation problems that can afflict either `gcc' or
|
||||
`g77'.
|
||||
|
||||
General Problems
|
||||
----------------
|
||||
|
||||
These problems can occur on most or all systems.
|
||||
|
||||
GNU C Required
|
||||
..............
|
||||
|
||||
Compiling `g77' requires GNU C, not just ANSI C. Fixing this
|
||||
wouldn't be very hard (just tedious), but the code using GNU extensions
|
||||
to the C language is expected to be rewritten for 0.6 anyway, so there
|
||||
are no plans for an interim fix.
|
||||
|
||||
This requirement does not mean you must already have `gcc' installed
|
||||
to build `g77'. As long as you have a working C compiler, you can use a
|
||||
"bootstrap" build to automate the process of first building `gcc' using
|
||||
the working C compiler you have, then building `g77' and rebuilding
|
||||
`gcc' using that just-built `gcc', and so on.
|
||||
|
||||
Patching GNU CC
|
||||
...............
|
||||
|
||||
`g77' no longer requires application of a patch file to the `gcc'
|
||||
compiler tree. In fact, no such patch file is distributed with `g77'.
|
||||
This is as of version 0.5.23 and `egcs' version 1.0.
|
||||
|
||||
Building GNU CC Necessary
|
||||
.........................
|
||||
|
||||
It should be possible to build the runtime without building `cc1'
|
||||
and other non-Fortran items, but, for now, an easy way to do that is
|
||||
not yet established.
|
||||
|
||||
Missing strtoul or bsearch

||||

||||

||||

||||
|
||||
Cleanup Kills Stage Directories
|
||||
...............................
|
||||
|
||||
It'd be helpful if `g77''s `Makefile.in' or `Make-lang.in' would
|
||||
create the various `stageN' directories and their subdirectories, so
|
||||
developers and expert installers wouldn't have to reconfigure after
|
||||
cleaning up.
|
||||
|
||||
That help has arrived as of version 0.5.23 of `g77' and version 1.1
|
||||
of `egcs'. Configuration itself no longer creates any particular
|
||||
directories that are unique to `g77'. The build procedures in
|
||||
`Make-lang.in' take care of that, on demand.
|
||||
|
||||
LANGUAGES Macro Ignored
|
||||
.......................
|
||||
|
||||
Prior to version 0.5.23 of `g77' and version 1.1 of `egcs', `g77'
|
||||
would sometimes ignore the absence of `f77' and `F77' in the
|
||||
`LANGUAGES' macro definition used for the `make' command being
|
||||
processed.
|
||||
|
||||
As of `g77' version 0.5.23 and `egcs' version 1.1, `g77' now obeys
|
||||
this macro in all relevant situations.
|
||||
|
||||
However, in versions of `gcc' through 2.8.1, non-`g77' portions of
|
||||
`gcc', such as `g++', are known to go ahead and perform various
|
||||
language-specific activities when their respective language strings do
|
||||
not appear in the `LANGUAGES' macro in effect during that invocation of
|
||||
`make'.
|
||||
|
||||
It is expected that these remaining problems will be fixed in a
|
||||
future version of `gcc'.
|
||||
|
||||
System-specific Problems
|
||||
------------------------
|
||||
|
||||
A linker bug on some versions of AIX 4.1 might prevent building when
|
||||
`g77' is built within `gcc'. It might also occur when building within
|
||||
`egcs'.
|
||||
|
||||
Cross-compiler Problems
|
||||
-----------------------
|
||||
|
||||
`g77' has been in alpha testing since September of 1992, and in
|
||||
public beta testing since February of 1995. Alpha testing was done by
|
||||
a small number of people worldwide on a fairly wide variety of
|
||||
machines, involving self-compilation in most or all cases. Beta
|
||||
testing has been done primarily via self-compilation, but in more and
|
||||
more cases, cross-compilation (and "criss-cross compilation", where a
|
||||
version of a compiler is built on one machine to run on a second and
|
||||
generate code that runs on a third) has been tried and has succeeded,
|
||||
to varying extents.
|
||||
|
||||
Generally, `g77' can be ported to any configuration to which `gcc',
|
||||
`f2c', and `libf2c' can be ported and made to work together, aside from
|
||||
the known problems described in this manual. If you want to port `g77'
|
||||
to a particular configuration, you should first make sure `gcc' and
|
||||
`libf2c' can be ported to that configuration before focusing on `g77',
|
||||
because `g77' is so dependent on them.
|
||||
|
||||
Even for cases where `gcc' and `libf2c' work, you might run into
|
||||
problems with cross-compilation on certain machines, for several
|
||||
reasons.
|
||||
|
||||
* There is one known bug (a design bug to be fixed in 0.6) that
|
||||
prevents configuration of `g77' as a cross-compiler in some cases,
|
||||
though there are assumptions made during configuration that
|
||||
probably make doing non-self-hosting builds a hassle, requiring
|
||||
manual intervention.
|
||||
|
||||
* `gcc' might still have some trouble being configured for certain
|
||||
combinations of machines. For example, it might not know how to
|
||||
handle floating-point constants.
|
||||
|
||||
* Improvements to the way `libg2c' is built could make building
|
||||
`g77' as a cross-compiler easier--for example, passing and using
|
||||
`$(LD)' and `$(AR)' in the appropriate ways. (This is improved in
|
||||
the `egcs' version of `g77', especially as of version 1.1.)
|
||||
|
||||
* There are still some challenges putting together the right
|
||||
run-time libraries (needed by `libg2c') for a target system,
|
||||
depending on the systems involved in the configuration. (This is
|
||||
a general problem with cross-compilation, and with `gcc' in
|
||||
particular.)
|
||||
|
||||
Changing Settings Before Building
|
||||
=================================
|
||||
|
||||
Here are some internal `g77' settings that can be changed by editing
|
||||
source files in `egcs/gcc/f/' before building.
|
||||
|
||||
This information, and perhaps even these settings, represent
|
||||
stop-gap solutions to problems people doing various ports of `g77' have
|
||||
encountered. As such, none of the following information is expected to
|
||||
be pertinent in future versions of `g77'.
|
||||
|
||||
Larger File Unit Numbers
|
||||
------------------------
|
||||
|
||||
As distributed, whether as part of `f2c' or `g77', `libf2c' accepts
|
||||
file unit numbers only in the range 0 through 99. For example, a
|
||||
statement such as `WRITE (UNIT=100)' causes a run-time crash in
|
||||
`libf2c', because the unit number, 100, is out of range.
|
||||
|
||||
If you know that Fortran programs at your installation require the
|
||||
use of unit numbers higher than 99, you can change the value of the
|
||||
`MXUNIT' macro, which represents the maximum unit number, to an
|
||||
appropriately higher value.
|
||||
|
||||
To do this, edit the file `egcs/libf2c/libI77/fio.h' in your `g77'
|
||||
source tree, changing the following line:
|
||||
|
||||
#define MXUNIT 100
|
||||
|
||||
Change the line so that the value of `MXUNIT' is defined to be at
|
||||
least one *greater* than the maximum unit number used by the Fortran
|
||||
programs on your system.
|
||||
|
||||
(For example, a program that does `WRITE (UNIT=255)' would require
|
||||
`MXUNIT' set to at least 256 to avoid crashing.)
|
||||
|
||||
Then build or rebuild `g77' as appropriate.
|
||||
|
||||
*Note:* Changing this macro has *no* effect on other limits your
|
||||
system might place on the number of files open at the same time. That
|
||||
is, the macro might allow a program to do `WRITE (UNIT=100)', but the
|
||||
library and operating system underlying `libf2c' might disallow it if
|
||||
many other files have already been opened (via `OPEN' or implicitly via
|
||||
`READ', `WRITE', and so on). Information on how to increase these
|
||||
other limits should be found in your system's documentation.
|
||||
|
||||
Always Flush Output
|
||||
-------------------
|
||||
|
||||
Some Fortran programs require output (writes) to be flushed to the
|
||||
operating system (under UNIX, via the `fflush()' library call) so that
|
||||
errors, such as disk full, are immediately flagged via the relevant
|
||||
`ERR=' and `IOSTAT=' mechanism, instead of such errors being flagged
|
||||
later as subsequent writes occur, forcing the previously written data
|
||||
to disk, or when the file is closed.
|
||||
|
||||
Essentially, the difference can be viewed as synchronous error
|
||||
reporting (immediate flagging of errors during writes) versus
|
||||
asynchronous, or, more precisely, buffered error reporting (detection
|
||||
of errors might be delayed).
|
||||
|
||||
`libg2c' supports flagging write errors immediately when it is built
|
||||
with the `ALWAYS_FLUSH' macro defined. This results in a `libg2c' that
|
||||
runs slower, sometimes quite a bit slower, under certain
|
||||
circumstances--for example, accessing files via the networked file
|
||||
system NFS--but the effect can be more reliable, robust file I/O.
|
||||
|
||||
If you know that Fortran programs requiring this level of precision
|
||||
of error reporting are to be compiled using the version of `g77' you
|
||||
are building, you might wish to modify the `g77' source tree so that
|
||||
the version of `libg2c' is built with the `ALWAYS_FLUSH' macro defined,
|
||||
enabling this behavior.
|
||||
|
||||
To do this, find this line in `egcs/libf2c/f2c.h' in your `g77'
|
||||
source tree:
|
||||
|
||||
/* #define ALWAYS_FLUSH */
|
||||
|
||||
Remove the leading `/* ', so the line begins with `#define', and the
|
||||
trailing ` */'.
|
||||
|
||||
Then build or rebuild `g77' as appropriate.
|
||||
|
||||
Maximum Stackable Size
|
||||
----------------------
|
||||
|
||||
`g77', on most machines, puts many variables and arrays on the stack
|
||||
where possible, and can be configured (by changing
|
||||
`FFECOM_sizeMAXSTACKITEM' in `egcs/gcc/f/com.c') to force smaller-sized
|
||||
entities into static storage (saving on stack space) or permit
|
||||
larger-sized entities to be put on the stack (which can improve
|
||||
run-time performance, as it presents more opportunities for the GBE to
|
||||
optimize the generated code).
|
||||
|
||||
*Note:* Putting more variables and arrays on the stack might cause
|
||||
problems due to system-dependent limits on stack size. Also, the value
|
||||
of `FFECOM_sizeMAXSTACKITEM' has no effect on automatic variables and
|
||||
arrays. *Note But-bugs::, for more information.
|
||||
|
||||
Floating-point Bit Patterns
|
||||
---------------------------
|
||||
|
||||
The `g77' build will crash if an attempt is made to build it as a
|
||||
cross-compiler for a target when `g77' cannot reliably determine the
|
||||
bit pattern of floating-point constants for the target. Planned
|
||||
improvements for version 0.6 of `g77' will give it the capabilities it
|
||||
needs to not have to crash the build but rather generate correct code
|
||||
for the target. (Currently, `g77' would generate bad code under such
|
||||
circumstances if it didn't crash during the build, e.g. when compiling
|
||||
a source file that does something like `EQUIVALENCE (I,R)' and `DATA
|
||||
R/9.43578/'.)
|
||||
|
||||
Initialization of Large Aggregate Areas
|
||||
---------------------------------------
|
||||
|
||||
A warning message is issued when `g77' sees code that provides
|
||||
initial values (e.g. via `DATA') to an aggregate area (`COMMON' or
|
||||
`EQUIVALENCE', or even a large enough array or `CHARACTER' variable)
|
||||
that is large enough to increase `g77''s compile time by roughly a
|
||||
factor of 10.
|
||||
|
||||
This size currently is quite small, since `g77' currently has a
|
||||
known bug requiring too much memory and time to handle such cases. In
|
||||
`egcs/gcc/f/data.c', the macro `FFEDATA_sizeTOO_BIG_INIT_' is defined
|
||||
to the minimum size for the warning to appear. The size is specified
|
||||
in storage units, which can be bytes, words, or whatever, on a
|
||||
case-by-case basis.
|
||||
|
||||
After changing this macro definition, you must (of course) rebuild
|
||||
and reinstall `g77' for the change to take effect.
|
||||
|
||||
Note that, as of version 0.5.18, improvements have reduced the scope
|
||||
of the problem for *sparse* initialization of large arrays, especially
|
||||
those with large, contiguous uninitialized areas. However, the warning
|
||||
is issued at a point prior to when `g77' knows whether the
|
||||
initialization is sparse, and delaying the warning could mean it is
|
||||
produced too late to be helpful.
|
||||
|
||||
Therefore, the macro definition should not be adjusted to reflect
|
||||
sparse cases. Instead, adjust it to generate the warning when densely
|
||||
initialized arrays begin to cause responses noticeably slower than
|
||||
linear performance would suggest.
|
||||
|
||||
Alpha Problems Fixed
|
||||
--------------------
|
||||
|
||||
`g77' used to warn when it was used to compile Fortran code for a
|
||||
target configuration that is not basically a 32-bit machine (such as an
|
||||
Alpha, which is a 64-bit machine, especially if it has a 64-bit
|
||||
operating system running on it). That was because `g77' was known to
|
||||
not work properly on such configurations.
|
||||
|
||||
As of version 0.5.20, `g77' is believed to work well enough on such
|
||||
systems. So, the warning is no longer needed or provided.
|
||||
|
||||
However, support for 64-bit systems, especially in areas such as
|
||||
cross-compilation and handling of intrinsics, is still incomplete. The
|
||||
symptoms are believed to be compile-time diagnostics rather than the
|
||||
generation of bad code. It is hoped that version 0.6 will completely
|
||||
support 64-bit systems.
